Question

match the following cells with their appropriate ploidy level. a human cheek cell silk glands of the commercial silkworm, containing over a million copies of the genome rye grass with four sets of chromosomes a bacterium with a single circular chromosome diploid haploid tetraploid polyploid

Explanation:

• Human cheek cells are somatic cells with two sets of chromosomes, so they are diploid.
• The silk glands of the commercial silkworm with over a million copies of the genome are polyploid as they have many sets of chromosomes.
• Rye grass with four sets of chromosomes is tetraploid as tetra - means four.
• A bacterium with a single circular chromosome is haploid as it has only one set of genetic material.

Answer:

• a human cheek cell: diploid
• silk glands of the commercial silkworm, containing over a million copies of the genome: polyploid
• rye grass with four sets of chromosomes: tetraploid
• a bacterium with a single circular chromosome: haploid
